It is important that pressure or blows are applied in line with the axis of the pole.

- MANUAL INSTALLATION: it is preferable to use a manual pile-driver.

- MECHANICAL INSTALLATION: it is preferable to use a hydraulic percussion or friction pole driver, rather than a hammer system.

¤ In difficult ground (very dry soil, rock strata, etc.), use a water planting device or a perforator in order to facilitate driving the poles into the ground.

¤ When planting with a sledgehammer (whether manual or mechanical), use a sacrificial driving block, available as an accessory, in order to avoid damaging the pole end.

- DEPTH IN THE GROUND: in addition to the cross-section of the pole, it is the depth to which it is driven into the ground that determines the optimum stability of the trellising. With profiled steel poles, the minimum depth must be 60 cm for poles under a height of 2 m. For poles of 2 m or more, apply the rule of 1/3 in the ground and 2/3 above ground. In the event of this being impossible, reduce the gap between poles.
